摘要：
The H(alpha) profile of 21Com (A3p,SrCrEu) has been fitted to synthetic hydrogen profiles to derive the surface gravity of this star. A model of gravity log g = 3.75 +/- 0.25 best reproduces the observed profile for the effective temperature of 21Com. The derived gravity is characteristic of a luminosity class IV for the temperature regime considered.
